IMPROVEMENT lN TOOLS FOR FORMING THE NECKS OF BOTTLES.

Specification forming part of Letters Patent No. 37,142, dated December9, 1862.

To all whom it may concern:

Be it known that I, LEVI F. SMITH, of Stonington, in the State ofConnecticut, have invented certain new and useful Improvements in Toolsfor Forming the Necks of Bottles; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying drawin g, and to the letters of referencemarked thereon.

In the annexed drawing, making part of this specification, A representsthe body of the tool, which consists of a piece of metal in the shape ofa bow. and made sufficiently thin that the two ends of the bow may bereadily forced together by the fingers of one hand.

13 represents a stem running centrally between the two sides of the bodyA, as shown in the figures, and provided, as seen at its outer end, witha center piece, D, for forming the inside of the neck of the bottle, asis usual in the manufacture of bottles.

C 0 represent jaws upon the ends of the bow or body A very similar tothose used in the ordinary tool for forming bottle-necks.

F represents a pin secured to the stem B and passing through the sidesof the bow A, as seen. Between the ends of the bow and the stem B willbe seen small coiled wire springs, which are used for the purpose ofassisting in shoving the two ends of the bow apart after they have oncebeen drawn together.

E represents a lever, which is made in the shape represented in thefigures, and which is pivoted, as shown at a, to the stem B. One end ofthis lever passes into the end of the center piece, which is providedwith a suitable opening for receiving it, while the other end passesthrough a loop, which is formed upon one of the sides of the bow, asshown at d. Upon the end of the lever which enters the center piecethere is formed a projecting shoulder, as seen at m, which shoulderpasses through a slot or opening in one side of the center piece. Whenthe two sides of the bow are pressed together, the shoulder protrudesthrough the opening in the center piece, and when the two sides areallowed or forced to separate, the shoulder is drawn back into thecenter piece.

The object of this tool is to form upon the inside of bottle-necksshoulders, against which elastic stoppers may catch to prevent them fromdrawing out readily.

It will be seen that by inserting the center piece, D, in the neck ofthe bottle when the glass or other material is in a pliable state andforcing the two sides of the bow together that the shoulder atm willprotrude and press against the glass on the inside of the neck, and thusform a shoulder or enlargement on the inside of the neck near the mouthof the bottle when the tool is turned around or the bottle revolved.When the two sides of the bow separate, the shoulder at no draws in andallows the bottle to be easily drawn from the center piece.

The stopper to be used with the bottle thus formed is made ofindia-rubber. When it is once inserted, the rubber expands so that itcatches under the shoulder in the neck, and is made tighter by pressurefrom the inside of the bottle.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The lever E, constructed, used, and operated substantially as and forthe purpose specified.

2. The combination of the lever E with the center piece, D, the severalparts being arranged as specified, for forming shoulders inbottle-necks, as set forth.
